GREEN LAKE - The historic Heidel House on Green Lake will close its doors May 20, according to a news report.

Fiore Companies, the entity that owns Heidel House, announced Friday the decision to shut down the resort on May 20, according to the Ripon Commonwealth Press. The newspaper also reports the company has yet to find a buyer for the property.

The hotel experienced declining revenue and fewer guests, which led to Fiore's decision to discontinue operations at the resort, the newspaper reported citing a news release.

Fiore Chief Operating Officer Stacy Nemeth said despite efforts to revitalize the house and attract new customers, Fiore could not keep up with the operating costs, according to the Commonwealth Press report.

Nemeth was not immediately available late Friday afternoon for comment.

The Heidel House was built in 1890 as a private estate before converting into a family-run resort in 1945. The Madison-based Fiore Companies bought the property in the 1980s, initially keeping its management staff, but as Fiore started dropping hotels from its portfolio, it contracted with Marcus Hotels & Resorts in 2014 to run the facility.

In March 2016, Fiore announced it was putting Heidel House up for sale as it was trying to unload its last remaining hotel property, Nemeth told USA TODAY NETWORK-Wisconsin at the time.
